Application fi1ed April24, 1914. Serial No. 834,082.

To all whom it may concern:

Be it known that I, FLOYD D. S'rowE, of WVilmington, in the county of Newcastle and in the State of Delaware, have invented a certain new and useful Improvement in Slide-Former Machines, and do hereby declare that the following is a full, clear, and exact description thereof. I

My invention relates particularly to a machine for forming slides used for closing the bung-holes of kegs, such for example, as

powder kegs.

The object of my invention is to provide a machine in which blanks of the proper shape are formed into slides which have side flanges adapted to cooperate with sides of the ears attached to bung-holes upon kegs of the above character, and which willprovide the slides with suitable lettering and stamped figures which are used for identify ing the particular keg and the character of the contents. Further objects of my invention will appear from a consideration ofthe particular apparatus which is described in detail hereinafter.

While my invention is capable of being carried out in many different ways, for the purpose of illustration I have shown only one form of my invention in the accom' panying drawings, in which,

Figure 1 is a front elevation of a slide former made in accordance with my invention;

Fig. 2 is a plan view of the lower or stationary portion of the same;

Fig. 3 is a vertical section through a portion of the apparatus taken in the position of line a-a in Fig. 2;

Fig. 4 is a front elevation of the portion of the machine shown in Fig. 2;

Fig. 5 is a vertical section enlarged of certain parts shown in Fig. 3;

Fig. 6 is a vertical elevation partly in section of the upper reciprocating portion of the machine,

Fig. 7 is a side elevation of the same,

Fig. 8 is a bottom view of the parts shown in Fig. 6 and,

Fig. 9 is a side elevation of one of the kicker arms.

Fig. 10 is a plan view of the unformed blank;

Fig. 11 is a similar view of the formed blank, and

Fig. 12 is an elevation of the article shown in Fig. 11. p

In the drawings I have shown a main frame 1 having a reciprocating plunger 2, which receives a stem 3 of a male die, which comprises a four-sided sleeve 4 fitting over a reduced end 5 on the stem 2 and yieldingly moved downward a slight distance from the stem by means of springs 6. Screws 7, of which there are three, hold the four-sided sleeve 4 upon the reduced extension 5. At the bottom of the sleeve 4 on the two sides thereof there are inwardly curved recesses 8 for a purpose to be hereinafter described, and upon the bottom of the sleeve 4 there is a plate 9 which extends out beyond the lower edges of the curved recesses 8 for a purpose also to be hereinafter described. The plate 9 is held in place by four screws 10 which connect the same to the sleeve 4. The cent'er of the stem 3 at the lower portion is extended to a position somewhat above the lowest portion of the plate 9 so as to receive a male lettering die 11 which is secured in place by a bolt 12 extending downwardly through the center of the stem 3 and screwthreaded intothe top of said male die 11. At its two sides the stem 3 has a pair of lateral extensions 13 to receive vertical guides 14, which are screw-threaded thereto and which have cylindrical guiding surfaces 15 at their lower ends. The guides 14 are held in their adjusted positions by screws 16, which extend into the lateral extensions 13. In the reciprocation of the plunger 2, the guides 14 reciprocatein holes 17 which pass through a pair of lateral guide plates 18 at tached to thetop of folder plates 19 supported on a bed plate 20 secured to the main frame. These folder plates 19 are secured to the bed plate 20 by screws 21. Beneath the folder plates 19 the bed plate 20 has recesses 22 atthe two sides of the same into which are secured by means of screws 23, holders 24 for a pair of rocker arms 25. Each of these rocker arms has a pivot 26 which rotates in a socket in one of the holdv ers 24, while at its free or movable end the under surface of the rocker arms 25.

The folding arm 27 is designed to force the edge of the blank into one of the recesses 8 f while the guiding arm 28 is designed to move the rocker arm 25, so as to force the arm 27 into said recess 8. The arms 28 are moved by curved surfaces 29, located in the underside of a stripper plate 30. This stripper plate 30 in the forming of the blank occupies a position immediately below the blank. The function of the guides 14 is not only to assist in guiding the relatively movable parts with regard to each other, but is also to act as an adjustable auxiliary actuating means for the rocker arms 25. This additional actuating means is particularly advantageous where the curved surfaces 29 have become worn to some degree through continued operation of the rocker arms by contact with the arms 28. In the center of the stripper plate 30 and supported upon the bed plate 20, there is a female lettering die 31, which is held upon the same by a bolt 32 which passes upwardly into the bed 20 through the center of a pipe 33 which is screw-threaded at its upper end in the bottom of the bed 20. A washer or spacing block 34 fits over the bolt 32 between the head thereof and the lower end of the pipe 33. The lower end of the pipe 33 is also screwthreaded to receive a spring collar 35, the purpose of which is to support an inner spring 36 and an outer spring 37. Upon the top of the outer spring 37 there is a collar 38 to which there are connected three pins 39 which extend upwardly to and contact with the under surface of the stripper plate 30. The force of the spring 37 therefore maintains the stripper plate 30 at all times pressed against the under surface of the blank which is carried over the edge of the plate 9 during the forming of the blank into its proper shape and before it is discharged from the machine. Supported upon the top of the inner spring 36 there is a collar 40 which is integral with a plate 41 having at tached thereto four pins 42, the upper ends of which extend to and contact with the The inner spring 36 therefore exercises its force upward to move the rocker arms 25 up wardly whenever an upward movement is permitted by the position of the reciprocating male die. The blank when formed is automatically released from the machine by the following mechanism: Upon the top of the bed 20 there is riveted a pair of posts 43 the upper ends of which provide bearings for a shaft 44 extending out through the sides of the posts 43 and receiving on its ends collars 45 and 46. The collar 46 has a recess in its inner face to receive a coil spring 47, which normally tends to move the shaft 44 in such a direction as to cause a pair of kicker arms 48 attached to the shaft '44 to move toward their vertical position.

The other collar 45 has a recess in its under ace to cooperate with a pin 49 so as to limit the degree of movement of the kicker arms 48. Each of the kicker arms 48 has at its lower end a projection 50 to throw the formed blank out of the machine at the end f the forming operation, andfeach of said kicker arms 48 also has at its upper end an actuating arm 51 Which co'liperates with a plate 52 held in position by screws 53 pass ing through the same and into the stems 3.

In the upper face of the stripper plate 30 there are also supported three dating or lettering dies 54 which operate against three aluminum plugs 55 (Fig. 8) which are supported in the under face of the sleeve 4. v

Preferably the machine as shown is so located as to support the various parts at an angle to the horizontal, so that the narrow end of the formed blank will be directed toward the lower side of the machine.

In the operation of the machine a flat blank 56, having the shape shown in Fig. 10 will be inserted in the machine when its sides will contact with the lateral guides 18 in such a way that the edges of the blank are supported upon the top of the folder plates 19. When next the plunger 2 is moved downwardly with its attached male die the plate 9 will move downwardly until it contacts with the upper surface of the blank 56. Thereafter the plate 9 will continue its movement downwardly thus pressing the blank 56 down below the level of the folder plates 19, the free edges of which will cause the edges of the blank 56 to be folded upwardly in a vertical direction. The continued downward movement of the plunger 2 will bring the blank56 with its folded edges to a level below the edges of the folder plates 19 where the rocker arms 25 will bring the folder arms 27 against the folded edges of the blank 56 so as to operate the same upwardly int-o recesses 8 over the top surfaces of the plate 9. The rocker arms 25 are moved in this manner not only by the curved surfaces 29, but also by the guides 14. Finally in the downward movement of the plunger 2 the male lettering die 1.1 co operates with the female lettering die 31 to give thev impression of a letter in the body of the blank 56, and at the same time the three dating or lettering dies 54 impress their numbers or letters into the blank in cotiperation .with the aluminum plugs 55. When the upward movement of the plunger 2 now begins the stripper plate 30 follows the formed blank upwardly with the male tion of the rocker arms is such as to. permit the continued upward movement of thean'ale die andthe plate 9 attached thereto With the blank 56 folded over the same Without any interference from the rocker arms 25. As soon as the plate 9 has passed above and beyond the stripper plate 30, the springs 6 between the sleeve 4- and the stem 3 will cause the sleeve 4L and its attached blank to move downwardly a short distanceso as tomove the formed blank beyond the level ofthe male die and thus release the formed blank 56 from any engagementwith theraised surface of the male die; Atthispoi'nt the plate 52- comes into contiactwith the upper ends of the kicker arms d8 thus violently forcing the lowerends 50 thereof against the, edge of the formed blank 56-, so as to kick the sameoif of the male die and the plate 9, after Which owing to theincline of the parts the formed blank falls downward by gravity to a receptacle or any other apparatus designed to assist in the removal of the formed blanks. 1

WVhile I have described my. invention above in detail, I Wish it to be understood that manyfchanges may be madether'ein Without departing from the spirit of my invention.
